1-My projection distance is fixed at 20 feet and I have a 100 inch screen. Is it possible to adjust the zoom to cover only 100 inches?

Not even close. Per Optoma's website, this projector has only a 1.2 zoom. If you need to be that far back and display that small of a screen, your choice of projectors gets very small--perhaps nonexistent. I have an older Panasonic with a 2.0 zoom, and I can display 110" from over 17' away. But even my projector would only go down to 120" at 20 feet. You need a bigger screen!

More than likely not. We are about 12 feet back and can just focus on our 130" screen.

I would call their tech support. I bought this projector and LOVE IT. I called them with the screen size and the distance and they told me exactly where to place it and how far down it had to hang.

You can change the image size by moving the projector closer or further from the screen (or white wall). I can fill up a portable widescreen screen easily. The resolution is good too. I deal in detail so it's important to keep the detail more than the size.

The image will fill the 18 x 24 space. You just have to get the projector far enough away and focus it properly. It just takes some fooling around with until you get it the way you want it.

Go to www.viewsonic.com. Find the pro8300. There is a distance chart. For 120", its 10feet. 150", a bit further. However, this Awesome machine allows you to adjust without being exact on the distance recommended. Hope this helps. if not, then I'll try and get the answer you're looking for.

We mounted our projected at church about 5-6 feet from the wall, and I think you can reduce the screen size by using the keystone feature. Hope this helps.

There is no adjustment using the screen, as far as I know. The adjustment on the computer I made under internet options accessories, I think. It has been a long time. We made the print as large as possible, and the contrast for those with low vision. I was using Microsoft so not sure about other operating systems and adjustments. This screen just magnifies it more. What didn't work for my mother was that her problem was more with clarity and contrast than size. It didn't help her to just to magnify. She has optic nerve damage. I hope this will help someone.

that would depend on the how big of a screen you want and what angle you are projecting. I have my projector mounted on the ceiling and projecting a 110" image on my wall. I have rather good definition although the angle form the ceiling mount makes one corner of the projection not as clear as the rest,(there is a lens focus that you adjust for different distances) but from what I have read on every projector this is a very common problem. I would recommend this projector over any other. between it's value and clarity its a great buy for a big screen without the big price. let me know if you have any other questions.

You must have a projector, the projector has a plug in for computer, camera, ipod, PS3, and more, I use my screen just for that reason. You can plug in most anything and project from 30 feet away, but just use the 100 inch screen. Armando 949-500-9165

First extend it to full length, then adjust the focus. And you can only use it for distant objects. I don't have it now but I remember it do require some trial and error.

Just looked at mine at I would say it zooms up to about 18 feet ... So go example I zoomed right in on something and had it crystal clear and it was 18 feet away.... Hope that helps?

Short throw lens, it has focus but not Zoom. You can find more technical details regarding to this projector on www.projectorcentral.com. You have to set the size of the image controlling the distance from the screen which is relatively short.

I just set this up w/ a 110" screen @ a throw distance of 10.5 ft. Some pixellation is noticeable at 720p but very minor. It really depends on your source. 1080p looks amazing. The projector is a light cannon and picture is amazing. You won't regret it.

The projector has a throw ratio of .69-.83, meaning for a 100" screen the projector will need to be 69-83 inches away from the screen. I put mine as far back as I could so I wouldn't have to do too much keystone adjustment, since that distorts the image the more you use it.

Yes there is a zoom. The 170, 127, 90 is only in reference to the wide angle settings. These control how much of the scene is in view from side to side. The actual zoom to control how close the object is to you is available on this unit.

The projector doesn't have a zoom. The adjustment on the lens is for focus only. You would have to move the projector to a spot to fit your screen and then focus the picture. Our use for this projector is as a portable option.

my setup is 7' high and 10' from the screen. The lens is in maximum zoom position to attain about 120" screensize.
